Abstract

A deflection compensating device relates to roll type coaters of paper making equipment. A metering roll of the deflection compensating device is arranged between two frames, a groove-shaped single swing arm and an L-shaped pressurizing arm are sequentially movably connected onto one frame, two ends of a turbine screw lifter are respectively connected onto the frame and the single swing arm, cylinders are respectively movably connected onto the single swing arm and the pressurizing arm, another L-shaped pressurizing arm is movably connected onto the other frame, two ends of a fountain roll is respectively fixed between the pressurizing arms of the two frames, the fountain roll is positioned on the lower portion of the metering roll, and two wedged limiting devices are respectively fixed onto two bearing blocks of the metering roll and the fountain roll. The deflection compensating device can eliminate deflection generated between the metering roll and the fountain roll during operation, leads the two rolls to be tightly adhered, and accordingly improves coating quality of paper.

Description

Flexibility compensating device

Technical field

The utility model relates to paper making equipment, specially refers to the print roll coating device.

Background technology

Be to improve the quality of paper, or, also will carry out deep processing paper because of the special requirement of paper.Normally by paper being coated with, applying glue, being coated with water or other medium meets the demands.And the evenness of filming directly influences the quality of sheet processing.The print roll coating device is a kind of equipment that can be coated with processing to paper, it mainly by be arranged in the coatings tank dip roll with the coating that extracts by the metering of the nip between dip roll and metering roll after, transfer to by pressure roller by metering roll and to be pressurized on the paper of metering roll, realize coating process.Because the length of roller is very long, the linear pressure during work between metering roll and the dip roll and produce amount of deflection, it is inconsistent to cause two roll surfaces to be fitted, and causes to transfer to metering roll to coat thickness inconsistent, thereby causes coating evenness poor.In the present existing print roll coating device, be that dip roll is installed on the L shaped arm that is positioned on the frame, by the relative metering roll of dip roll is made travel scissors, the middle section of two rollers is fitted carry out deflection compensation, this deflection compensation mode is subjected to the restriction of linear pressure between two rollers, and cause that the binding face distortion is different, and the became uneven of filming when metering roll shifts is even, and finally still influence is coated with evenness.

Summary of the invention

The purpose of this utility model is to provide a kind of flexibility compensating device, and it is a kind of device that produces amount of deflection when working between metering roll and the dip roll of eliminating.

The technical solution of the utility model is:

The utility model comprises two frames, a metering roll and a dip roll, a metering roll is separately fixed between two frames by two bearing blocks respectively, dip roll is below metering roll, the simple pendulum arm of a groove shape of loose joint on the described frame, L shaped arm of loose joint on the simple pendulum arm, one end of dip roll is on the bearing block of arm, one end of cylinder is actively socketed on the end of arm, the other end is actively socketed on the lower end of simple pendulum arm, one end of turbine screw elevator is connected on the frame, the other end is connected on the simple pendulum arm, the wedge shape stopping means is on the bearing block of dip roll one end, another L shaped arm of loose joint on another frame, the other end of dip roll is connecting on the arm on another bearing block, one end of another cylinder is actively socketed on the arm, and the other end is actively socketed on the frame, and another wedge shape stopping means is on the bearing block of the dip roll other end.

Two wedges are up and down arranged on the tank bracket of wedge shape stopping means, be connected with an adjusting screw(rod) on the following wedge.

Advantage of the present utility model is: because the utility model is provided with simple pendulum arm and two cylinders, two cylinders can make dip roll be adjacent to or throw off metering roll, when dip roll and metering roll are adjacent to, turbine screw rod crane rotates dip roll by simple pendulum arm and moves relative to the metering roll axle center, generation owing to amount of deflection when having eliminated the applying of two rollers causes the not tight drawback of applying, make applying stressed evenly, coating can form the quality that filming of uniformity improved paper product after by the nip metering roll.

The specific embodiment

Referring to accompanying drawing embodiment, the utility model is described in further detail.

Among Fig. 1-2, the two ends of metering roll 1 are installed in respectively is fixed in frame 7,12 bearing block 13, between 14, the simple pendulum arm 8 of a groove shape of loose joint on the frame 7, L shaped arm 5 of loose joint on the simple pendulum arm 8, one end of dip roll 4 is installed on the bearing block 15 of arm 5, L shaped arm 10 of loose joint on the frame 12, a bearing block 16 has been installed on the arm 10, the other end of dip roll 4 is installed on the bearing block 16, dip roll 4 is below metering roll 1, one end of cylinder 6 is actively socketed on the end of arm 5, the other end is actively socketed on the lower end of simple pendulum arm 8, and an end of turbine screw elevator 9 is connected on the frame 7, and the other end is connected on the simple pendulum arm 8, one end of another cylinder 11 is actively socketed on the simple pendulum arm 10, the other end is actively socketed on the frame 12, and a wedge shape stopping means 3 is installed on the bearing block 15, and another stopping means 3 is installed on the bearing block 12, two wedges up and down are housed on the framework of wedge shape stopping means 3, and adjusting screw(rod) 2 is connected down on the wedge.

During work, open cylinder 6 and cylinder 11, the piston rod of its cylinder 6 and cylinder 11 stretches out simultaneously, make dip roll 4 enter station work, when metering roll 1 produces amount of deflection with dip roll 4 stress deformations, make metering roll 1 and dip roll 4 applying imprecisions, rotary turbine screw elevator 9, simple pendulum arm 8, cylinder 6 and cylinder 11, arm 5 and arm 10 movement therewith, dip roll 4 is reversed accordingly around metering roll 4, thereby obtain to center on mutually the effect of fitting, compensated the amount of deflection of metering roll 1 with dip roll 4.

Rotate the adjusting screw(rod) 2 on the wedge shape stopping means 3, lower wedge block is driven go up voussoir to rise or descend and make dip roll 4 rise or descend to guarantee linear pressure unanimity between metering roll 1 and the dip roll 4.Work finishes, and cylinder 6 and cylinder 11 put down, and arm 5 and arm 10 are moved down, and dip roll 4 moves down with metering roll 1 thereupon and breaks away from.
